New fMRI images of unsedated dogs represent a first peak into what dogs are thinking and open a door into canine cognition and social cognition in other species
Fido's expressive face, including those longing puppy-dog eyes, may lead owners to wonder what exactly is going on in that doggy's head. Scientists decided to find out, using brain scans to explore the minds of our canine friends.
The researchers, who detailed their findings May 2 in the open-access journal PLoS ONE, were interested in understanding the human-dog relationship from the four-legged perspective.
"When we saw those first [brain] images, it was unlike anything else," said lead researcher Gregory Berns in a video interview posted online. "Nobody, as far as I know, had ever captured images of a dog's brain that wasn't sedated. This was [a] fully awake, unrestrained dog, here we have a picture for the first time ever of her brain," added Berns, who is director of the Emory University Center for Neuropolicy.
